V BAKERS ovma To allwhomz'tmay conoerm Be it known-tint I, lVILHELM ZIEMsEN, master locksmith,'a citizen of the Republic .of Germany, residing at Brunswick, Germany, 12 .Grordelingerstrasse, have'invented certa n new and useful Improvements in My invention refers to bakers ovens and more especially to novel means for heating two baking chambers selectively from a single burner by means of oil.

One object of the invention is to provide a heating burner mounted at the of a swinging pipe which is connected to a fuel supply arranged between the two. baking chambers so that from one baking chamber to the other.

Another object of my invention is the provision of a burner selectively operable. 1n one of'a plurality of baking chambers in which the fuel is atomized by fluid pressure.

Another object is to provide means for automatically reducing the flame in said burner when the latter is withdrawn from a baking chamber.

Still another object is to provide means whereby the fluid'pressure utilized in atomizing the fuel is generated in one of the ovens.

The structure embodying my invention is shown by way of example in the annexed drawings, in which:

Figure 1 1s a front elevation of a bakers OVGIl.

Figure 2 is a cross section view of one. of the heating chambers.

Figure 3 is a longitudinal sectional View of the swinging connection from the supply pipes to the burner.

Referring in detail to the drawings, the oven 2 is provided with two baking chambers 1 between which is arranged a vertical portion of a stationary fuel'supply pipe 7 which leads to a liquid fuel tank 3, located preferably above the level of the burner so as to supply the fuel to the burner by pressure of gravity.

Leading portion of the alignment therewith is the vertical portion of a steam supply pipe 1 1. The ends of these pipes are in communication with a swinging joint 8 comprising a solid metal upwardly toward the vertical Specification of Letters Patent.

portion having sockets at its upper and lower ends by means of which it is journaled on the ends of the fuel supply and steam supply 'pipesi respectively. From one side 'oint 8 and in communication respecof the tively with the upper and lower sockets of said joint extend hollow arms 19 and 18 attached to and communicating with the up per and lower sides of the burner. The mode. attachment of said arms with the burneris such as to give said burner freedom, of movement relative thereto.

srAr s ;.PA TENT v o -c 1 Within the baking chamber 1 and preferably nearthe roof thereof is a steam generating coil 12 supplied with water from the supply container'll through the conduit 10. Any starts of pressure may be used to lift the water. The steam on its way to the The ends offlthe fuel and water supply pipes 7 and lt'with the sockets of the joint 8, are closed but are provided near the ends with oppositely aligned transverse openings 20 and 21 of such size as to give free communication between the supply pipes and the hollow arms 19 and 18 when the joint is in the position shown in Figure 3 or at anangle of 180 thereto. At intermediate angles of swing the apertures are more or less out of registry with the openings of the hollow arms 19 and 18, a limited communication being, however, maintained bymeans of a small groove 22 running circumferentially around each of the sockets in the plane of the apertures 20 and 21.

By this construction-both the fuel and fluid pressure supply to the burner are cut down while the burner is being swung and the disadvantage of having a huge flame exposed outside the baking chamber is avoided. I A system of valves in the supply pipes gives control of the size of the flame issuing from the burner at all times. The gravity tank 3jis adapted to be filled by any convenient means such as the pump 5 drawing from the container 6. i

For preliminary starting with a coldoven it is of course obvious that the steam must be gotten up by some auxiliary source of heat such as a wood or paper fire built in the baking chamber.

I claim:

1. In a bakers oven in combination, two baking chambers, a swinging pipe joint between said chambers, a burner adapted to be oscillated about said joint so as to alternatively'heat one or the other chamber, and
